Liquid separating device



s s O R K R LIQUID SEPARATING DEVICE Filed Dec. 2'?, 1958 rari j?. Kosa INVENTOR Patented idiota.l d, i f' entre naar. erica This invention relates to separating devices, and its general object is to provide a device of that character, which is primarily designed for attachment to a milk bottle ofthe usual type for separating the cream from the milk, in a manner whereby the cream in its entirety is removed from the bottle without fear of commingling the same vwith the milk, as by the"- use of'my device the cream is gently forced from the bottle by air pumped therein, thereby eliminating tilting or otherwise moving the bottle which. generally causes the milk and cream to become mixed, with the result it will be seen that the cream can be separated and removed in aneasy and expeditious manner, with minimum eort on the part of the user.

A further object is to provide a separating device that has all of its parts connected together in a single unit, yet is simple in construction, inexpensive to manufacture, can be readily cleaned and mantained'in a sanitary condition, and is extremely eilcient in operation, use and service.

This invention also consists in certain other features o construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding "parts throughout the several views, and in which:

Figure 1 is a vertical sectional view taken through my device applied to a milk bottle.

Figure 2 is a fragmentary top plan view of the device per se, partly in section.

Figure 3 is a bottom plan view thereof.

Figure 4 is a. sectional view taken approximately on line t-t of Figure 2, looking in the direction of the arrows, with the device applied to the bottle.

Referring tothe drawing in detail, the letter A indicates a container which is shown as being a. milk bottle oi' the usual construction, in that it includes a neck having an annular shoulder interiorly oi the lip thereof. and while my device is primarily designed for removing cream from milk bottles, it will be obvious that it can be used for removing any kind of liquid, from various typesof containers, for transferring the liquid therefrom to another container, vessel or the like.

l'l'he device in the form as shownl includes a relatively thick disk like body l having formed 55 thereon and depending therefrom adjacent to the ((Cli. 2mm-51.5)

marginal edge thereof an annular rib of a size and shape to fit within the shoulder of the mouth of the bottle, to be seated therein, in a manner to provide a leak prooi connection between the device and bottle, as will be apparent upon inspection of Figures l and i, as the body is preferably made from relatively soft rubber, but it may be made from some suitable hard ma terial and in that event a rubber washer would be used between the rib 2 and the shoulder of y@ the mouth.

Disposed about the upper marginal edge of the body l and extending outwardly therefrom is an annular lange il adapted to `receive an annular harige il formed on the skirt o oi a compressible 35 bulb a, the latter being of substantially cylindrical formation and is secured to the body by a hanged ring l, in a leak prooi manner, as will be apparent.

Formed on the under suriace of the body i 2@ and depending centrally therefrom is a conical portion d within which is secured lthe upper end of a tube d that is disposed in depending relation with respect to the body and has its upper end communicating with a passage Il@ extending ra 255 dially of the body and opening through the side thereof, as best shown in Figure l. Mounted in the outlet end of the passage l@ is a tube li havo ing its outer end portion downwardly flared and beveled as shown, to provide a. spout. The tube 8 to has secured thereto a collar l2 to limit the movement thereof within the body and so that its upper endgwill be ush with the bottom ci the passage iil at all times, as shown, but of course it will be understood that the tube t can be of any 35 length,` it depending upon the use to which the device may be put, but when the device is used as a cream separator, the tube@ is preferably of a length so that its lower end will terminate `slightly above the cream line in a milk bottle 40 when the device is applied thereto, as shown.

The valve means for controlling the passage of air within the bottle to force the cream theref from is mounted directly on the body, and for that purpose, the body is formed with elongated 45 recesses in the upper and lower surfaces thereof that provide seats for intake and exhaust flap valves la and le respectively, that are secured within the recesses adjacent one of their ends, by a rivet or the like I. The ap valve I3 con- 50 trois an 'air inlet duct I6 that extends radially of the body with its inner end portion upwardly directed to open within the recess oi the valve I3, as best shown in Figure 4, while the valve M controls `an air duct il extending vertically o5 tioned that it is applied to e. bottle as. shown, and

upon alternately pressing and releasing the bulb air will be drawn within the bulb through the duct i@ end thence will be passed tugli the duct il, tbe valves it and it being opened by the slr to allow for the free p ainbut closing to prevent the return thereof,

therefore es the mesure builds up shove the cream, it will force the latter from the bottle through the tube e, message l@ end tube il.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

lt is to be understood that changes muy be made in the construction andvin the combination and arrangement oi the several parte, provided that suoli changes fell within the scope oi the appended claim.

t i claim is:

s: of the incoming" A liquid separating device compr a disk like body having a liquid new therein and recesses in the upper and lower laces thereof, annular means formed on and depending from the body and being irictionally receivable within a container for detachably securing the body thereto, a tube depending .from the inlet end ofthe ge for disposal `ivithin the container, a tube extending from theoutlet end o! the DBS- ssge and providing a pouring spout. a substantially cylindrical collapsible bulb rising from the marginal edge o! the body, means securing the bulb to the body to provide a leak proof connec` tion between the same, said body having a radially and vertically disposed air duct therein. said duct its radially disposed portion opening to the atmosphere g ze: Within the recess of seid upper face, seid he. en air duet extending vertically therethrough end having its lower end w *ze tbe recess of and the bulb to introduce eir vai tbe oonteiner for forcing liquid from the letter through the Y ge und said use velves tting and seated within the for controlling the ducts, und means ior connecting tbe liep valves together for securing7 them Within their recesses.
